Problems solved by technology

At present, the two sides of most of the tires that have been scrapped are almost intact, because the tire tread is severely worn, and for the sake of driving safety, they are abandoned and used, so a lot of money is spent.

Abstract

The invention relates to the technical field of rubber production and specifically relates to a pneumatic rubber tire. The pneumatic rubber tire is characterized by being prepared from the following raw materials in parts by weight: 20-30 parts of butadiene styrene rubber, 20-30 parts of natural rubber, 4-5 parts of zinc oxide, 10-12 parts of carbon black, 4-5 parts of silicon dioxide, 2-3 parts of isoprene, 1-3 parts of cross-linking agent, 2-3 parts of sulfur, 3-5 parts of stearic acid and 1-2 parts of anti-aging agent. The Tg of the isoprene copolymer elastomer of the pneumatic rubber tire is at least 30 DEG C lower than the Tg of other elastomers based on diene. The cross-linking agent is divinyl benzene or stannic chloride.

Description

[0001] technical field [0002] The invention relates to the technical field of rubber production, in particular to a pneumatic rubber tire. Background technique [0003] As an important part of the car, the car tire is an important part of the car to bear gravity, transmit traction force, braking force, steering force and bear the reaction force of the road surface. Its quality is directly related to personal and property safety. At present, both sides of most of the tires in the scrapped tires are almost intact, because the tire treads are seriously worn, and they are abandoned for driving safety, so they are spent in large quantities. [0004] It is highly desirable for tires to have good wet skid resistance, low rolling resistance and good wear characteristics. Highly resilient rubbers have traditionally been used in the manufacture of tire tread rubber compounds. On the other hand, in order to increase the wet skid resistance of tires, rubber which suffers large energ...
